Decatur, IL -- (SBWIRE) -- 03/30/2015 -- Performance and durability count. T/CCI customers rely on compressors to keep their vehicles running and their operators comfortable, even in the toughest environments. When a customer experiences issues with their compressors, the company is committed to fully investigate the situation and offer solutions that will keep everyone up and running.
While working with a customer who is contracted to provide ambulances to operations in Afghanistan, compressor failures were being reported. The following information was collected:
- Most failures were immediate or shortly after delivery
- Compressors showed extensive shoe damage
- Significant swash plate damage was also reported
T/CCI engineers worked closely with the customer to evaluate the conditions, the protocols, and the failure details in order to conduct a thorough evaluation of the situation. Testing included hot chamber testing with oil circulation studies, internal lab simulation, and onsite testing with the customer. The following conditions were present:
- Original refrigerant charge level was 7 lbs.
- Total compressor oil charge level was 6 oz. in the compressor and 5 oz. installed in the discharge line during assembly
- There was a darkened "star" pattern on all 10 shoes and a smudge through the center of the compression surface in an arc pattern
- Thermal migration during transport may be an issue
After completing a thorough situation analysis, the T/CCI engineers determined that the root cause of the failures was lack of lubrication between the swashplate and the "shoes."
